Forgiving pretty-print

What is the best way to pretty print a possibly malformed JSON string? (which is a very long string, impossible to validate and fix by eyes...)

Pretty printing should work, albeit partially, if JSON is malformed.

Just like web browser can render malformed HTML.

My challenge is JSON is malformed, but pretty-printing should still works. (probably to a limited extent)

I guess you could use JSON Formatter extension for chrome it will format it on screen but I don't know if how it would look like if you print it, worth a try though
